The last time I had to worry about installing Python packages was two years ago working with Enthought, NumPy and MayaVi2. That experience gave me lingering nightmares related to quirky behavior installing & updating Python packages in non-standard locations (in $HOME/usr/local2.6/, for example). Anyway, my work is taking me back to in...
How can I use the pyglet API for sound to play subsets of a sound file e.g. from 1 second in to 3.5seconds of a 6 second sound clip? I can load a sound file and play it, and can seek to the start of the interval desired, but am wondering how to stop playback at the point indicated? ...
I'm looking at existing python code that heavily uses Paramiko to do SSH and FTP. I need to allow the same code to work with some hosts that do not support a secure connection and over which I have no control. Is there a quick and easy way to do it via Paramiko, or do I need to step back, create some abstraction that supports both para...

Are their any ways to optimize Jython without resorting to profiling or significantly changing the code? Specifically are there any flags that can be passed to the compiler, or code hints in tight loops. ...

Simple Question ;) Is there a way to simply install the package using pip once you build it. Using easy_install I would simply build my package it (python setup.py build), then if I was happy do a easy_install . and this would dump the resulting egg into the right place. How do I do this using pip? ...

We have an older C++ tool that generates some python code automatically. I tried to slog through the C++ source tool, today and pretty much wanted to shoot my self. The thing is what i want to do, is clean up the source created by the tool and link the classes to our internal documentation system via adding sphinx tags. Now what i am w...
I'd like to run a PostgreSQL query in Python using psycopg2, which filters by a column of type timestamp without timezone. I have a long list of allowed values for the timestamp (rather than a range) and psycopg2 convenient handles arrays, so I thought that this should work: SELECT somestuff FROM mytable WHERE thetimestamp = ANY (%(time...
I want to develop a tool for my project using python. The requirements are: Embed a web server to let the user get some static files, but the traffic is not very high. User can configure the tool using http, I don't want a GUI page, I just need a RPC interface, like XML-RPC? or others? Besides the web server, the tool need some backgr...

I am going to apologize in advance for being extremely vague, but my knowledge in this area is somewhat limited so I don't know the neccessary "keywords" to make my point/question clear. Sorry. What I want to do is to find a way to obtain access to raw audio data as it is being output, say, when some external application is playing back...
I have a class in python that allows me to save a function (in a database) for later use. Now I need to have a method in the class that allows me to call this function on some arguments. Since I don't know how many arguments the function has ahead of time, I have to pass them in as list. This is where things fall apart because I can't fi...
